In bullet points: explain the difference between thermal energy, heat and temperature.

sergeinik [125]

Thermal Energy- is the energy that comes from heat. This heat is generated by the movement of tiny particles within an object. The faster these particles move, the more heat is generated.

Heat-energy is the result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases. Heat energy can be transferred from one object to another. The transfer or flow due to the difference in temperature between the two objects.

Temperature- is a measure of how hot or cold something is; specifically, a measure of the average kinetic energy of the particles in an object, which is a type of energy associated with motion.

An acetylene tank has a volume of 390.0 L. It is stored at a temperature of 23.5 °C and has a

xeze [42]

Considering the ideal gas law, there are 279.42 moles of acetylene in the tank.

<h3>Definition of ideal gas</h3>

Ideal gases are a simplification of real gases that is done to study them more easily. It is considered to be formed by point particles, do not interact with each other and move randomly. It is also considered that the molecules of an ideal gas, in themselves, do not occupy any volume.

<h3>Ideal gas law</h3>

An ideal gas is characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them constitutes the ideal gas law, an equation that relates the three variables if the amount of substance, number of moles n, remains constant and where R is the molar constant of gases:

P×V = n×R×T

<h3>Moles of acetylene</h3>

In this case, you know:

P= 1765 kPa= 17.4192 atm (being 101.325 kPa= 1 atm)
V= 390 L
n= ?
R= 0.082 $\frac{atmL}{molK}$
T= 23.5 °C= 296.5 K (being 0 °C= 273 K)

Replacing in the ideal gas law:

17.4192 atm× 390 L = n×0.082 $\frac{atmL}{molK}$ × 296.5 K

Solving:

$n=\frac{17.4192 atmx 390 L}{0.082 \frac{atmL}{molK}x296.5 L}$

<u><em>n= 279.42 moles</em></u>

Finally, there are 279.42 moles of acetylene in the tank.
